If you are like me and have been attempting to play "older" games using crossfire since Crimson release, you may have noticed an issue where the game will not boot if you are in fullscreen (crossfire enabled).

I have finally discovered the issue. 1440p monitors plus games with crossfire profiles created prior to Crimson will NOT WORK!

Here is a list of games:

Rocket League

Witcher 2

Diablo 3

X-Com Enemy Unknown

Many More....

I have confirmed this issue by switching my primary monitor to a 1080p monitor, and crossfire works without any issue. This was NOT an issue in drivers prior to Crimson. PLEASE AMD HELP!!!
